Apophyseal avulsion fractures of the pelvis and hip

Last revised by Yusra Sheikh on 09 Nov 2022

Apophyseal avulsion fractures of the pelvis and hip are relatively common among physically active adolescents and young adults.

Pelvic and hip apophyseal injuries typically occur in the 14 to 25 year age range.

Kicking sports, such as soccer, and gymnastics are frequently implicated.

Sudden forceful muscular contraction causes avulsion of the apophysis to which the tendon attaches.
